Answer:
0.6443
Step-by-step explanation:
Given the that:
P(Z < 0.37) ; using a standard normal distribution :
The probability can be obtained using several methods :
Using a standard normal distribution table ;
P(Z < 0.37) = obtain the value at the intersection where 0.3 is on the vertical axis and 0.07 on the horizontal axis of the Z distribution table
Hence,
P(Z < 0.37) = 0.6443

Grant spent half of his weekly allowance. Then he earned $5 back by doing the dishes. What is his weekly allowance if he ended with $15?
Answer:
Grant's weekly allowance is $20.
Step-by-step explanation:
We know that Grant ended with $15. We can say that Grant's weekly allowance is x.
x/2 + 5 = 15
Now to solve:
x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)
x/2 = 10
x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)
x = 20
Grant's weekly allowance is $20.
Amy is putting a new floor in her bathroom. She created a scale drawing of her bathroom floor using a scale of 1/3 inch= 1 foot. In the drawing, the bathroom measure 3 inches by 3 1/3 inches. Amy is purchasing squares tiles that measure 1/3 foot on each side. The cost of each tile is $3.00. How much will Amy pay for the tiles for bathroom floor
Answer:
$2,430
Step-by-step explanation:
Scale of the drawing = ⅓ in. to 1 ft
Measurement of the bathroom on paper = 3 in. by 3⅓ in.
Actual measurement of the bathroom:
3*3 = 9 ft
3⅓ * 3 = 10 ft
Area of the bathroom = 9*10 = 90 ft²
Let's find how many square tiles would cover 90 ft².
The side length of 1 tile is said to be ⅓ ft.
Therefore, the area of 1 tile would be ⅓*⅓ = ⅑ ft².
Number of tiles that would cover 90 ft² would be:
90/⅑ = 90*9
= 810 tiles
If 1 tile cost $3.00, therefore 810 tiles would cost:
810 * 3 = $2,430.

Answer:
Area of rectangular garden = lxb = 10*5
= 50 sq. inch
when area increases by six times
new area = 50*6 = 300 sq inches
now,
let x be increasement in both length and width
(5+x) (10+x) = 300
50 + 5x + 10x + x² = 300
x² + 15x - 250 = 0
x²+ 25x-10x -250 = 0
x(x+25) - 10 (x+25) = 0
( x-10) (x+25) = 0
either x + 25 =0
x = -25 length can be negative
0r x-10 = 0
x = 10
so 10 inches is increase on both side

a student earned a grade of 80% on a math test that had 20 problems how many problems on this test did the student answer correctly
Answer:
16
Step-by-step explanation:
To find 80% of 20, multiply .80 x 20
.80×20 = 16
This is how you multiply percentages--put the decimal point 2 places to the left, then multiply. In this case, you're looking at 80%, so move the decimal point two places to the left
80.0 becomes .80
Then multiply that by the number you're trying to find the percentage of
Does anyone know how to do these? I don't understand them at all... :(

Harry earned d dollars mowing lawns. He put 20% of his earnings in the bank and paid back $50.00 to his father. He spent
one-fifth of the remaining money on a video game. Which expression represents the amount he spent on the video game?
(0.20 - 10) dollars
(0.20 - 50) dollars
(0.160 + 10) dollars
(0.160 - 10) dollars
Answer:
(0.16d - 10) dollars
Step-by-step explanation:
"Harry earned d dollars mowing lawns. He put 20% of his earnings in the bank and paid back $50.00 to his father."
Start with d dollars.
He put 20% of d dollars in the bank. 20% of d is the same as 0.2d.
Now he has d - 0.2d = 0.8d
He paid his father $50.
Now he has 0.8d - 50
"He spent one-fifth of the remaining money on a video game. Which expression represents the amount he spent on the video game?"
He spent 1/5 of 0.8d - 50 on a video game, so he spent on the video game:
1/5 * (0.8d - 50) = 0.16d - 10
Answer: 0.16d - 10 dollars
(You forgot the "d" in the answers."
(0.16d - 10) dollars

work out the value of x
will give brainliest
Answer:
x = 35
Step-by-step explanation:
we know that all triangles add up to 180
you first need to make an expression in which the angles equal 180
105 + 140 + x = 180
145 + x = 180
subtract 145 from both sides
x = 35

Answer:
k is the slope of the graph.
Step-by-step explanation:
Which equation describes the line with a slope of 5 and a y-intercept of 4.
Answer:
The line should look like: y=5x+4
Step-by-step explanation:
The equation for slope-intercept form is y=mx+b, where m is your slope and b is your y-intercept.
Therefore, if we plug in the given values, our equation should look like the following:
y=5x+4
Answer:
y=5x+4
y=mx+b
